Our Journey

We started our journey parked in the neighborhood at the end of Kawaipuna St. There are three bunkers, two of which has a view, and one with a great view! The hike goes through the forest, and the trail also splits. One direction goes to a waterfall and the other loops up to the ridge. We took the ridge trail which lead us out of the forest and back towards the road. There are gradual inclines, but nothing too strenuous. After about an hour or so we saw the first bunker. The view was covered by trees! But don't be sad, there is another bunker further down at the end of the ridge. The view from there is beautiful spanning from Haaula all the way to Laie!





















Heading up past the neighbors. Follow the road.





















The trail goes left around the water tank.






















Follow the trail as there are some markers here and there.






















The trail splits here. We went up on the right side.






















After you get out of the forest, the view opens up!






















Continuing along the trail, heading to the first lookout point.






















The lookout point, and in the distance you can see the ridge on the left.






















Heading to the right, following the pink ribbons.






















The trail is starting to look like a Hawaii Kai hike. Lol






















We went up this way, then took a right to head up the ridge portion.






















Out on the ridge. The 360 view is amazing!






















Following the trail to the first bunker.






















Just having fun and looking back at the valley. Deep gulches with waterfalls, but we'll save that for next time.






















Going up some crumbly rocks and dirt.






















Admiring the view!






















The last bunker is at the end of that ridge!






















Single file line please!






















And inside the first bunker!


























Pretty cool bunker, but the view was blocked by the trees.






















Nothing really to see, so let's continue on to the second bunker.






















The brush got a little overgrown in this part of the hike.






















And reaching the second bunker.






















The view from the bunker was amazing!





























You can see Laie Point all the way to the left.


























Here's a spot where you can get a closer view!


























Last shot before we headed back. What a day!
